You need ribbed condoms for her pleasure – at least that’s what the commercials say.
Well science has decided that a rough member is essential for evolutionary survival.
Well, at least if you’re a fruit fly!
But before you reject having your sex life compared to a bugs, remember Charles Darwin, who spent eight years studying barnacles genitalia theorized, the male members complexities assist the male in “holding her securely.”
Evolutionary biologist Michal Polak of University of Cincinnati and co-author Arash Rashed confirmed Darwin right.
Published online in the Proceedings of the Royal Society B, “Microscale Laser Surgery Reveals Adaptive Function of Male intromittent Genitalia” Polak’s research demonstrated that in the fruit fly Drosophila bipectinata Duda, the tiny “intromittent” spines on the penis assisted them in copulation.
“We refer to these genital spines as intromittent because they insert [them] into female external genitalia during copulation, and not because they insert into the reproductive tract,” wrote Polak and Rashed.
A sample of poor flies were went under Polak’s laser to see how it affected sexual performance. A fruit fly circumcision?
Polak, an associate professor in the Department of Biological Sciences in McMicken College of Arts and Sciences at UC, used a laser ablation technique to remove the “intromittent” spines from virgin male D. bipectinata Duda fruit flies.
This image has been magnified to show an ablated spine and an intact spine.
When the spines were removed, the males experienced drastic reductions in ability to copulate and ability to compete against rival males for mates.
However, if the males were able to copulate, they found that insemination and fertilization rates were not significantly different.
Perhaps, this is not really good condom research. But then, if evolutionary psychology is right, then it follows that since 90 to 95% of our thinking is unconsciously influenced biologically then the evolutionary past may influence our behavior.
However, I do wonder if my sex life can be compared to fruit fly? Or were condom designers onto something?
Perhaps not – but it’s worth contemplating.
